[Javascript] Disable left mouse click and drag on images

[john at jwarner.com (John Warner)]

I'm not where I can double check myself right now, but I'm sure the
mouse Down event can be fired for an <img> tag. But this will be your
least effective method of stopping your images from being downloaded if
someone wants them. Getting around this requires the least amount of
knowledge on the part of the user.

Thanks for the comments so far guys.

One thing I was thinking of is this. In Javascript, can I detect what I
click on. So basically, on a Mousedown event, I want to know the
property of that object I have just clicked on, so is it text, a link,
and image......is there a way of doing this.

Can I detect if it is an image I have just left cliked on.......any
ideas.........
